Abstract (en)

[origin: EP2966849A1] Provided is a color adjustment apparatus, image display apparatus, and color adjustment method for adjusting color of a color image to enable easier distinction between objects shown in the image. A parameter defines a range of saturation to be adjusted within saturation before color adjustment and a range of change of the saturation after color adjustment compared to the saturation before color adjustment. The color adjustment apparatus calculates the saturation from an image signal, calculates the saturation after color adjustment according to the saturation before color adjustment such that the saturation in the range determined by the parameter increases/decreases by an amount determined by the parameter, and generates an image signal from the saturation after color change. By determining the parameter such that the saturation difference between prescribed colors is greater after color adjustment, the difference in color between a plurality of objects shown in the image is increased.
